This flute is made to the same specifications as the Shishida and Maruyama shinobue flutes. It is easy to play and produces good high-pitched sounds. Most beginners can play the low notes, but they often struggle with the high notes and the even higher "pi" sound. Many people are also unsure if the flute they are currently using is actually producing the correct sounds. This flute was created based on the opinions of instructors from various regions (easy to produce high-pitched sounds, clear high register, and affordable). It is recommended that beginners, rather than buying an expensive flute first, learn to produce the high-pitched sounds and high register, then go to a shop and try out different flutes to find one that suits them. (Some flutes may look good but not have a clear high register). Also, it seems that progress is faster if you start taking lessons after you can already produce some sounds. To prioritize ease of playing, sound, resonance, and affordability, there may be scratches, natural shapes, natural patterns, and natural bends. A 10mm ball is placed in the image for reference of the hole size, etc. Thickness: Approximately 19.5mm at the mouthpiece. Length: Approximately 45.7 cm Mouthpiece size: Approximately 14.5mm Thickness: Normal (Thicker flutes have better low-frequency resonance, while thinner flutes have better high-register sound) Wall Thickness: 2 out of 5 (Thicker walls produce better high-register sound and resonance, while thinner walls are easier to play) Pitch: Approximately between a "roppon-jaku" and a "roppon" flute. Range: Clear sound from the "tsutsune" (low register) to the high register 5. About Yaki-take (Burnt Bamboo): This is the best material for sound production among shinodake bamboo. Bamboo becomes harder and produces better sound when thoroughly burned. However, there are few materials that meet the conditions, and it is difficult to process. It is also characterized by even better sound production when made naturally. Bamboo grows by competing for light. Therefore, the bamboo that wins the competition for light is the most suitable for flutes. (I have been researching physics utilizing the laws of nature for many years, so I can identify bamboo that meets the right conditions.) About Suke-nuri Finish (Transparent Lacquer Finish): Because no pigments are used in the lacquer, it is easier to produce sound. Also, by carving grooves inside and allowing the lacquer to soak in, the sound becomes even easier to produce and the resonance improves. Please be aware: This flute produces very good high-pitched sounds and high register. When playing strongly, make sure there are no people around. Especially be careful around small children, the elderly, people with disabilities, and those who are not feeling well. Regarding Discounts: Due to being handmade, discounts are not possible.
